rstiki

rstiki is a minimalist single-file personal wiki using reStructuredText
syntax (via docutils) inspired by pwyky. It does not support authorship
indication, versioning, hierarchy, chrome/framing/templating or styling. It
leverages docutils/reStructuredText as the wiki syntax. As such, it's under
200 lines of code, and in a single file. You put it in a directory and it
runs.
